Tempstar offers a limited warranty on all functional parts; most units feature a 10-year warranty, according to the manufacturer, but this will vary among specific units. You must provide proof of yearly service, as well as your original purchase receipt, to qualify for warranty repairs. The manufacturer's "No Hassle Replacement" limited warranty replaces a unit in the event that a primary component such as a compressor or heat exchanger fails within the warranty period. That length of time varies from one year for base-level products to 10 years for the company's highest tier products.
